Subject: [PATCH] Adding dummy release functions to avoid warnings.

From: Vitaliy Ivanov <vitalivanov@gmail.com>

Trivial fix for #9690.
Added simple release functions that doing nothing.
Not sure whether we can leave it as is or to rework using platform_device helpers like platform_device_alloc.
This approach is used in many drivers.

Hi all,

Natalie reported that patch wasn't accepted.
Please check this out. If I need to correct it somehow then pls let me know.

Please see Documentation/kobject.txt - search for the text


I expect that
hgafb-convert-to-new-platform-driver-api-bugzilla-9689.patch which I
merged yesterday will help here.

Andrew,


Damn. I knew that everything is not so easy here;) Got it. Tnx.

But in such case there are _again_ many drivers that do implement such
fake functions. Again is because when I tried to port some usb driver
there were issues with locking that was not correct but many drivers
worked exactly this incorrect way.

Anyway, tnx for clarifying this.

V.
